hi i have just inherited a scott bonnar 45 cordless mower with catcher(model and serial nos 45 00141 and 45 0466.it has cordless printed on the mower and has the 2 piece handles which look like they cross over each other with the scott bonnar (SB) medallion in the lower middle section of the handles)the battery box is exposed.wondering what voltage battery it takes to see if it runs(confident as the mower presents well)are there many of this model around, and are they worth much?regards chisel 57 (new member)i am in melbourne.
